Resum

his paper insists in the need of understanding that science teaching has
had a development neither linear nor accumulative. This is a point of view assumed
in the presentation of both concepts and theories in some textbooks. In his sense, it
appearson the one handthat some questions concerning science have a direct
correspondence with the very particular contexts in which they were formulated and
on the other hand that a study of the approaches used in some textbooks to
present scientific concepts, can contribute to the design of strategiesprovided by
the history and philosophy of the science for science teaching in the classroom..
